White-crested Elaenia (Chilean)
SCI Name: Elaenia albiceps chilensis
chilensis
Chile (formerly spelled Chili). Etymology disputed; probably from Mapuche chilli  ends of the earth.
● Erroneous TL. Chile (= Manila, Philippines) (syn. Lalage nigra).
● Erroneous implied TL. Chile (= Bolivia) (Tangara).
● “Hellmayr is the most recent author who proposes to reject Molina’s name on the grounds that it is a composite between the present form and Jacana j. jacana. It must be remembered that a large percentage of the names of the 18^th century authors are composites, and if any degree of stability in nomenclature is to be attained the name must be fixed on one of the species to which the account applies, provided of course that the name is identifiable at all” (Peters 1934) (Vanellus).
